- WELCOME TO THE MULTI-DIMENSIONAL
- DATA VISUALIZATION DEMO
-
-
- This demonstration shows how you can visualize
- data in four or more dimensions using surface
- plotting, color, and animation. The demo displays
- an animation consisting of 20 surfaces representing
- a vibrating membrane. By default, the animation
- represents a four-dimensional data set; the X,
- Y, Z, and time dimensions are displayed.
-
- You can add a fifth dimension using color. Select
- "5 Dimensions" from the "Vertex Colors" sub-menu
- of the Options menu to represent a quantity that
- changes with time but which is not dependent on
- location.
-
- You can rotate the surface by positioning the mouse
- in the draw widget, holding down the left mouse button,
- and dragging the mouse.
